2. Consider a Cournot competition environment with one good and two firms, Firm 1 and Firm 2. The
(pure) strategy space of Firm 1 is S₁ = [0, 1], and the strategy s₁ of Firm 1 corresponds to the amount
of the good they produce. Similarly, the (pure) strategy space of Firm 2 is S2 = [0, 1], and the strategy
s2 of Firm 2 corresponds to the amount of the good they produce. If Firm 1 were to produce quantity
s₁ and Firm 2 were to produce quantity s2, the prevailing price in the good market would be 1 — 81 — 82,
the utility of Firm 1 would be their profit, u₁ (81, 82) = (1-81-82 - c)81, and the utility of Firm 2
would be their profit, u2($1, $2) = (1-81-82-c)s2, where 0 ≤ c< 1 is the marginal cost of production
for both firms.
(a) Find the pure-strategy Nash equilibria of this game.
(b) Are there other Nash equilibria in this game.
